2008-10-07IPVS: Move IPVS to net/netfilter/ipvsJulius Volz
Since IPVS now has partial IPv6 support, this patch moves IPVS from net/ipv4/ipvs to net/netfilter/ipvs. It's a result of: $ git mv net/ipv4/ipvs net/netfilter and adapting the relevant Kconfigs/Makefiles to the new path.

2008-09-05IPVS: Add IPv6 support flag to schedulersJulius Volz
Add 'supports_ipv6' flag to struct ip_vs_scheduler to indicate whether a scheduler supports IPv6. Set the flag to 1 in schedulers that work with IPv6, 0 otherwise. This flag is checked in a later patch while trying to add a service with a specific scheduler. Adjust debug in v6-supporting schedulers to work with both address families.

2008-09-05IPVS: Change IPVS data structures to support IPv6 addressesJulius Volz
Introduce new 'af' fields into IPVS data structures for specifying an entry's address family. Convert IP addresses to be of type union nf_inet_addr. Signed-off-by: Julius Volz <juliusv@google.com> Signed-off-by: Simon Horman <horms@verge.net.au>
2008-08-19ipvs: Fix race conditions in lblc schedulerSven Wegener
We can't access the cache entry outside of our critical read-locked region, because someone may free that entry. And we also need to check in the critical region wether the destination is still available, i.e. it's not in the trash. If we drop our reference counter, the destination can be purged from the trash at any time. Our caller only guarantees that no destination is moved to the trash, while we are scheduling. Also there is no need for our own rwlock, there is already one in the service structure for use in the schedulers.

2008-08-15ipvs: rename __ip_vs_wlc_schedule in lblc and lblcr schedulersSimon Horman
For the sake of clarity, rename __ip_vs_wlc_schedule() in lblc.c to __ip_vs_lblc_schedule() and the version in lblcr.c to __ip_vs_lblc_schedule(). I guess the original name stuck from a copy and paste. Cc: Sven Wegener <sven.wegener@stealer.net> Signed-off-by: Simon Horman <horms@verge.net.au>
2008-08-15ipvs: Only call init_service, update_service and done_service for schedulers ↵Sven Wegener
if defined There are schedulers that only schedule based on data available in the service or destination structures and they don't need any persistent storage or initialization routine. These schedulers currently provide dummy functions for the init_service, update_service and/or done_service functions. For the init_service and done_service cases we already have code that only calls these functions, if the scheduler provides them. Do the same for the update_service case and remove the dummy functions from all schedulers. Signed-off-by: Sven Wegener <sven.wegener@stealer.net> Signed-off-by: Simon Horman <horms@verge.net.au>

2008-01-28[IPVS]: Switch to using ctl_paths.Pavel Emelyanov
The feature of ipvs ctls is that the net/ipv4/vs path is common for core ipvs ctls and for two schedulers, so I make it exported and re-use it in modules. Two other .c files required linux/sysctl.h to make the extern declaration of this path compile well.

2008-01-28[NET]: Convert init_timer into setup_timerPavel Emelyanov
Many-many code in the kernel initialized the timer->function and timer->data together with calling init_timer(timer). There is already a helper for this. Use it for networking code. The patch is HUGE, but makes the code 130 lines shorter (98 insertions(+), 228 deletions(-)).

2007-12-05[IPVS]: Don't leak sysctl tables if the scheduler registration fails.Pavel Emelyanov
In case we load lblc or lblcr module we can leak some sysctl tables if the call to register_ip_vs_scheduler() fails. I've looked at the register_ip_vs_scheduler() code and saw, that the only reason to fail is the name collision, so I think that with some 3rd party schedulers this becomes a relevant issue. No?

2007-11-19[IPVS]: Move remaining sysctl handlers over to CTL_UNNUMBEREDSimon Horman

2007-02-14[PATCH] sysctl: remove insert_at_head from register_sysctlEric W. Biederman
The semantic effect of insert_at_head is that it would allow new registered sysctl entries to override existing sysctl entries of the same name. Which is pain for caching and the proc interface never implemented. I have done an audit and discovered that none of the current users of register_sysctl care as (excpet for directories) they do not register duplicate sysctl entries. So this patch simply removes the support for overriding existing entries in the sys_sysctl interface since no one uses it or cares and it makes future enhancments harder. Signed-off-by: Eric W.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
